Here scribe 2 of 𝓟 initially wrote to as if to write “and to their wives and their children”, but then he overwrote the o of to with an h and continued writing inline eir, thus replacing to with their. Clearly, his correction was immediate. He expected the preposition to (which had just occurred twice in “to their lands and to their houses”) to occur before “their wives and children”. But the preposition is not always repeated in this context, as can be seen in the previous chapter:
Summary: Maintain in Alma 3:1 the immediately corrected reading in 𝓟 for which the preposition to does not occur before “their wives and their children”.
